Current vs. Fair-Map Representation: How Gerrymandering Distorts Congressional Power
This chart compares the number of Democratic House seats in several states under current congressional maps versus the estimated number of seats each state would hold under a neutral, nonpartisan fair map. The data highlights how gerrymandering shifts representation away from proportional statewide vote share — with Texas, Florida, North Carolina, and Ohio showing the largest disparities.
This chart displays the difference between the number of Democratic seats won under current congressional maps versus the estimated number of seats Democrats would hold under a fair, non-gerrymandered map. States under Republican-drawn maps show significant underrepresentation for Democrats, especially Texas, Florida, North Carolina, and Ohio. States with Democratic gerrymanders, such as Illinois, show modest overrepresentation.
